Are you planning to install new subwoofers with your home theatre system? Learn more about what they are and how you can maximise your purchase.
Subwoofers
A subwoofer is a woofer – that is, a loudspeaker driver that is made to produce sounds with low frequency. A subwoofer is designed to reproduce low- pitched audio frequencies called bass. Subwoofers, also called LFE or point one channel, are composed of one or more woofers that are mounted in an enclosure of loudspeaker. The enclosure is usually made of wood and can withstand air pressure and prevent getting deformed.
Using a subwoofer augments the bass capability of the main speakers. It allows the bass to be smaller all without the sacrifice of low frequency capability.
It is incorrect to assume that a subwoofer automatically provides better bass sound than large conventional speakers. However, some recordings have very low frequency content that most conventional loudspeakers cannot handle on their own.
Where are subwoofers used?
A subwoofer is generally used in:
- home audio
- car audio
- cinema sound
- sound reinforcement
- full range system
- aux- fed subwoofers
- directional bass
- vertical array
- rear delay array
- end- fire array
- delayed- shaded array
- directional enclosure
- bass instrument amplification
In the past, setting up a subwoofer required a ton of guessing. However, newer subwoofer models now feature internal amps, EQ systems and room correction software, making it easy to set up and integrate a subwoofer with your loudspeakers.
Upgrading Your Subwoofers
If you currently have a wired subwoofer, with one RCA- style cable running to it, you can most likely upgrade it. It can be part of an HTIB, a 5.1 system or a soundbar with a wired sub.
The wireless subwoofers that come with soundbars are usually proprietary and therefore cannot be upgraded.
If you are looking to add a subwoofer to your home theatre or audio system, but don’t have a receiver, HTIB or soundbar, you may be able to use your TV. Some TVs have an output for a subwoofer. If yours does not, you may still be able to use the TV’s audio output (which all TV sets have). Check the owner’s manual and see if using the audio output will disable the TVs speakers. If it doesn’t and does audio output along with internal speakers, then you can add your sub there.
